Page 12: Service Connections
The service connections on the top of the FlightDAQ2 cover the supply gas, purge gas, calibrate and reference ports. These connections can be made either by 1/8” Swagelok compression fittings or Chell AS205 quick disconnects. These fittings can be interchanged as they both mate with the M5 feature in the top plate. -

Page 15: Internal Valving
4. Internal Valving The flightDAQ2 contains the necessary valving to purge the measurement lines of the flightDAQ2 and to perform a re-zero – even when the measurement lines are subject to pressures. The schematics below illustrates the function of the internal valves. There are two states of the scanner shuttle valve –... -

6. flightDAQ Configuration Webserver 6.1. Introduction. The flightDAQ web Configuration provides the means of setting up, calibrating and demonstrating the flightDAQ unit from a standard PC with an ethernet port and browser. The software is divided by tabs into seven areas of functionality, namely 'Setup’, 'Live data', 'Calibration', 'DTC Information’, ‘Advanced’, ‘Timestamp’, ‘Abs Cal’... -

Page 22: The 'Setup' Page
6.3. The 'Setup' Page 6.3.1. Introduction The 'Setup’ page shows all of the flightDAQ's main operating parameters. Setup is divided into different categories by function, and each category is detailed separately in the following. 6.3.2. Data Streaming The ‘Data Streaming’ section allows the user to change settings that affect all three communication protocols, and allows the user to choose the protocol that is to be used, along with the data transfer rate and the number of channels. -

6.4. 'Live Data' Page Figure 5.6 shows the 'Live Data' page of the webserver, selected for a 64-channel pressure scanner. Figure 5.6, Live Data Page The live data page is a means to demonstrating the correct operation of flightDAQ and testing the unit's calibration. -
Page 26: Calibration' Page
6.5. 'Calibration' Page The 'Calibration' page allows access to flightDAQ’s existing non-DTC calibration coefficients and provides a means to acquiring live calibration data and calculating new coefficients. The loading and saving of tests are also possible from this tab. Calibrations may either be 3 temperature based for a temperature calibration, or by unchecking the 'Temperature Cal.' checkbox, a non-temperature calibration may be performed at a single temperature. - Page 27 Control Function Temperature tickbox and radio Select at which temperature point the unit is currently been calibrated buttons Applied Pressure The engineering units pressure setpoints - user entered, or set to standard values (+/- FS, +/-0.5FS, 0) by clicking 'Defaults' Pressure (16 bit FS) The 16-bit unsigned representation of the pressure setpoints, calculated by the software...

6.6. 'DTC Information’ Page The 'DTC Functions' page gives the user access to some information regarding the attached DTC scanner. The scanner voltages for temperature and excitation may be read and the position of the calibration shuttle valve determined as either being in 'RUN' or 'CAL.' mode. Also, the information contained in the scanner header may be displayed. -
Page 29: Advanced' Page
6.7. ‘Advanced’ Page The advanced page contains functions that will change the how the flightDAQ acts and how it applies various calculations to its data, this page should only be used by users who fully understand what they are changing. 6.7.1. -
Page 30: Advanced Communication Settings
6.7.2. Advanced communication settings The flightDAQ has several more advanced communication options available, but these features are unlikely to be used by an everyday user and as such should generally be left as default settings. Figure 5.10, Advanced communication settings 'Gateway’... -
Page 31: Miscellaneous
6.7.4. Miscellaneous The remaining parameters are edited via the Miscellaneous group shown in Figure 5.11. The scanner type should always be set to the type of scanner installed in the flightDAQ to ensure proper operation of the system. If the flightDAQ is a DTC variant and DTC mode is to be used, the 'Use DTC' checkbox should be checked. - Page 32 If I-Daq detected, use raw If checked, this replaces the normal polynomial calibration function with a ‘raw’ linear calibration function whenever an I-Daq is present in the flightDAQ. 'Sensistor in circuit' If checked, keeps the sensistor in circuit for a DTC scanner. In normal operation this control should be left unchecked.

Page 33: Span And Zero Coefficients
6.7.5. Span and Zero Coefficients This section displays the Span and Zero coefficients currently stored within the flightDAQ as a result of a linear calibration. Figure 5.12, Span and zero coefficients 6.8. Timestamp This page allows the user to edit the timestamp settings of the flightDAQ. This timestamp will allow the user to get millisecond level accuracy timestamps on the data packets. -
Page 34: Abs Cal
‘get PC time’ This button allows the user to get the timestamp from the PC time of the PC they are using. This can be used as a base time for the timestamps if the user is not using PTP. In the first box it will show the timestamp and in the second box it displays the timestamp converted date/time to make it easier to understand. -

For more details on hardware trigger timing a technical paper is available – Chell document no. 900118 (this paper was developed for the CANdaq but applies to the flightDAQ as well). - Page 36 8. Service and Calibration 8.1. Service There are no user serviceable parts inside the instruments. Should any difficulties be encountered in the use of the flightDAQ, it is recommended that you contact Chell Instruments Ltd for advice and instructions. 8.2. Calibration Calibration is recommended on an annual basis and Chell Instruments Ltd.
